bEECIFICATIOlI formingpart of Letters Eatent No. 745,827, dated December1, 1903.

Application filed January 19, 1903. Serial No. 139,713. (No model.)

To (LZZ- 207mm, it may concern:

Be it known that I, ERNEST BARTON HACK, a subject of the King of GreatBritain, residing in the city and county of Denver and State ofColorado, have invented certain new and useful Improvementsiu Valves;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in valves.

My objects are to provide an easily and quickly opened device, to avoidfriction at the point of contact with the flow-channel, to provide asimple device having few wearing parts, and to produce a valve of thefaucet variety capable of efficient use with chemicals or solvents ofmetals and other liquids; and to these ends the invention consists ofthe features, arrangements,and combinations hereinafter described andclaimed, all of which will be fully understood by reference to theaccompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical section taken through myimproved faucet-valve. Fig. 2 is a top or plan view of the same. Fig. 3is a fragmentary detail View, on a larger scale, illustrating the outerextremity of the swinging frame and showing an adjustingscrew forregulating the position of the pin con meeting the extremities of theframe-arms.

The same reference characters indicate the same parts in all the views.

Let A designate the casing, provided with an apertu'red base A forsecuring the device to a suitable support. The casing may, however, besecured in any other suitable manner. The base of the valve is providedwith an inlet-passage A one extremity of which is surrounded by a seat Afor the gland B, which is secured to the disk B by a screw 13. A rod D,forming a valve-stem, is connected with a valve-disk at C and passesthrough an opening formed in the plug L, screwed into aninteriorly-threaded part DI of the casing, said threaded part beinglocated beyond the discharge-channel A. Pivotally connected with the rodor stem D where it projects through the plug L is a lever composed ofarms G and F, fulcrumed at J on an exteriorly-located stirrup-shapedswinging frame composed of two arms H, pivotally connected beyond thecasing by the fulcrum-pin J and spaced by a sleeve or tube J,surrounding the pin between the said arm extremities. The oppositeextremities of the arms H are pivoted to the casing exteriorly, as shownat K.

When the valve is closed, the parts are in the position shown by fulllines in Fig. 1. To open the valve, it is only necessary to raise thelever-arm F,whcn the parts will be thrown to the position shown bydotted lines in Fig. 1. To close the valve, the movement of thelever-arm is reversed.

In order to make compensating provision for the wear of the valve-glandB, I provide adjusting-screws M, threaded in the outer extremities ofarms J and engaging the pin J, whose extremities engage slots N, formedin the arms J. As the gland wears the screws M are turned to throw thepin inwardlytoward the valve, whereby the valve-stem is actuated toforce the gland tightly against the valve-seat when the valve is closed,by virtue of the connection between the manipulating-lever and thevalve-stem.

Having thus described my invention, what I claim is The combination witha casing, of avalve located therein and provided with a stem movable ina straight line to allow the valve to open and close, a lever connectedwith the outer extremity of the stem, a swinging frame mountedexteriorly on the casing, said frame having two arms provided withslotted outer portions, a pin connecting the two arms and engaging saidslots, the lever being fulcrumed on said pin, and adjusting-screwsthreaded in the arms of the swinging frame and engaging said pin.

In testimony whereof I affix my signature in presence of two witnesses.

ERNEST BARTON HACK.
